Credibility & transparency
We publish sources, computation rules, and privacy boundaries so results are easy to audit.
- •Sources: based on international standards such as SI definitions and widely used references (BIPM, NIST, IUPAC).
- •Method: conversions are deterministic scaling with fixed factors and double-precision arithmetic.
- •Privacy: inputs stay in the browser; no value is stored or transmitted.
- •Updates: factors and references are reviewed and updated when standards change.
